vb.net编程工具是什么

vb.net编程工具是：Microsoft Visual Studio 2008

1、Microsoft Visual Studio 2008是面向Windows Vista、Office 2007、Web 2.0的下一代开发工具，代号“Orcas”，是对Visual Studio 2005一次及时、全面的升级。

2、VS2008引入了250多个新特性，整合了对象、关系型数据、XML访问方式,语言更简洁。

3、使用Visual Studio 2008可以高效开发Windows应用。

4、设计器中可以实时反映变更,XAML中智能感知功能可以提高开发效率。

5、Visual Studio 2008支持项目模板、调试器和部署程序。

6、Visual Studio 2008可以高效开发Web应用，集成了AJAX 1.0，包含AJAX项目模板，它还可以高效开发Office应用和Mobile应用。

Q1: 用VB.NET编一个模拟袖珍计算器的完整程序

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim c As Char

c = Trim(TextBox3.Text)

Select Case c

Case "+"

TextBox4.Text = Val(TextBox1.Text) + Val(TextBox2.Text)

Case "-"

TextBox4.Text = Val(TextBox1.Text) - Val(TextBox2.Text)

Case "*"

TextBox4.Text = Val(TextBox1.Text) * Val(TextBox2.Text)

Case "\"

If Val(TextBox2.Text) = 0 Then

MsgBox("分母为0")

Else

TextBox4.Text = Val(TextBox1.Text) \ Val(TextBox2.Text)

End If

Case "/"

If Val(TextBox2.Text) = 0 Then

MsgBox("分母为0")

Else

TextBox4.Text = Val(TextBox1.Text) / Val(TextBox2.Text)

End If

End Select

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

End

End Sub

End Class

Q3: VB.NET 产生设计器错误后 过程全部失效

Name是窗体的名称，窗体名称只能在设计窗体时在窗体属性中修改，一旦修改，是只读的，在运行时不能再次修改，因此Me.Name = "Form2" 是错误的，因为它是只读的，但窗体在界面的 Caption 属性不是只读属性，它是可以在运行时修改的，你可以这样：Me.Caption = "Form2"。
